CSM will close the address and data latches, and it will begin erasing
the block indicated on the address pins. During programming/erase,
the device will respond only to the READ STATUS REGISTER, PROGRAM
SUSPEND, or ERASE SUSPEND commands. It will output status register
data on the rising edge of ADV#, or on the rising clock edge when
ADV# is LOW during synchronous burst mode, or on the falling edge
of OE# or CE#, whichever occurs last.
